UPGRADING
NEW FEATURES/CHANGES
====================
-Samba AD with MIT Kerberos
---------------------------
-After four years of development, Samba finally supports compiling and
-running Samba AD with MIT Kerberos. You can enable it with:
+net ads setspn
+---------------
- ./configure --with-system-mitkrb5
+There is a new 'net ads setspn' sub command for managing Windows SPN(s)
+on the AD. This command aims to give the basic functionaility that is
+provided on windows by 'setspn.exe' e.g. ability to add, delete and list
+Windows SPN(s) stored in a Windows AD Computer object.
-Samba requires version 1.15.1 of MIT Kerberos to build with AD DC support.
-The krb5-devel and krb5-server packages are required.
-The feature set is not on par with with the Heimdal build but the most important
-things, like forest and external trusts, are working. Samba uses the KDC binary
-provided by MIT Kerberos.
+The format of the command is:
-Missing features, compared to Heimdal, are:
- * PKINIT support
- * S4U2SELF/S4U2PROXY support
- * RODC support (not fully working with Heimdal either)
+net ads setspn list [machine]
+net ads setspn [add | delete ] SPN [machine]
-The Samba AD process will take care of starting the MIT KDC and it will load a
-KDB (Kerberos Database) driver to access the Samba AD database. When
-provisioning an AD DC using 'samba-tool' it will take care of creating a correct
-kdc.conf file for the MIT KDC. Note that 'samba-tool' will overwrite the system
-kdc.conf by default. It is possible to use a different location during
-provision. You should consult the 'samba-tool' help and smb.conf manpage for
-details.
+'machine' is the name of the computer account on the AD that is to be managed.
+If 'machine' is not specified the name of the 'client' running the command
+is used instead.
+The format of a Windows SPN is
+ 'serviceclass/host:port/servicename' (servicename and port are optional)
-Authentication and Authorization audit support
-----------------------------------------------
+serviceclass/host is generally sufficient to specify a host based service.
-Detailed authentication and authorization audit information is now
-logged to Samba's debug logs under the "auth_audit" debug class,
-including in particular the client IP address triggering the audit
-line. Additionally, if Samba is compiled against the jansson JSON
-library, a JSON representation is logged under the "auth_json_audit"
-debug class.
+net ads keytab changes
+----------------------
+net ads keytab add no longer attempts to convert the passed serviceclass
+(e.g. nfs, html etc.) into a Windows SPN which is added to the Windows AD
+computer object. By default just the keytab file is modified.
-Audit support is comprehensive for all authentication and
-authorisation of user accounts in the Samba Active Directory Domain
-Controller, as well as the implicit authentication in password
-changes. In the file server and classic/NT4 domain controller, NTLM
-authentication, SMB and RPC authorization is covered, however password
-changes are not at this stage, and this support is not currently
-backed by a testsuite.
+A new keytab subcommand 'add_update_ads' has been added to preserve the
+legacy behaviour. However the new 'net ads setspn add' subcommand should
+really be used instead.
+net ads keytab create no longer tries to generate SPN(s) from existing
+entries in a keytab file. If it is required to add Windows SPN(s) then
+'net ads setspn add' should be used instead.
-Query record for open file or directory
----------------------------------------
-
-The record attached to an open file or directory in Samba can be
-queried through the 'net tdb locking' command. In clustered Samba this
-can be useful to determine the file or directory triggering
-corresponding "hot" record warnings in ctdb.
-
+REMOVED FEATURES
+================
-Parameter changes
------------------
-The "strict sync" global parameter has been changed from
-a default of "no" to "yes". This means smbd will by default
-obey client requests to synchronize unwritten data in operating
-system buffers safely onto disk. This is a safer default setting
-for modern SMB1/2/3 clients.
smb.conf changes
================
- Parameter Name Description Default
- -------------- ----------- -------
- auth event notification New parameter no
- auth methods Deprecated
- map untrusted to domain Deprecated
- strict sync Default changed yes
-
-Removal of lpcfg_register_defaults_hook()
------------------------------------------
-
-The undocumented and unsupported function lpcfg_register_defaults_hook()
-that was used by external projects to call into Samba and modify
-smb.conf default parameter settings has been removed. If your project
-was using this call please raise the issue on
-samba-technical@lists.samba.org in order to design a supported
-way of obtaining the same functionality.
-
-Change of loadable module interface
------------------------------------
-
-The _init function of all loadable modules in Samba has changed
-from:
-
-NTSTATUS _init(void);
-
-to:
-
-NTSTATUS _init(TALLOC_CTX *);
+ Parameter Name Description Default
+ -------------- ----------- -------
-This allows a program loading a module to pass in a long-lived
-talloc context (which must be guaranteed to be alive for the
-lifetime of the module). This allows modules to avoid use of
-the talloc_autofree_context() (which is inherently thread-unsafe)
-and still be valgrind-clean on exit. Modules that don't need to
-free long-lived data on exist should use the NULL talloc context.
